China Tourmaline Powder Suppliers - High-Quality Functional Mineral from Reliable Factory

WANCHENG MINERAL, a leading factory and trusted supplier of tourmaline powder in China, offers high-quality functional mineral powder derived from premium tourmaline ore. Our meticulous production process includes cleaning, crushing, grinding, classification, and rigorous quality inspection to ensure the best possible product. Tourmaline, a unique borosilicate mineral, contains various elements such as silicon, aluminum, boron, iron, and more, which contribute to its multifunctional properties.

Our tourmaline powder stands out from ordinary mineral fillers not just for its filler performance but for its diverse applications across multiple industries. It serves as a key ingredient in negative ion powder, far infrared powder, tourmaline ceramic balls, functional masterbatches, mineral coatings, water treatment solutions, cosmetic powders, textile treatments, and composite materials. Different industries have specific requirements for fineness, purity, color, and functional tests, making it crucial to select the appropriate grade for optimal downstream performance.

At WANCHENG MINERAL, we provide tourmaline powder in various mesh sizes, including 100 mesh, 200 mesh, 325 mesh, 600 mesh, 800 mesh, 1250 mesh, and customized specifications to meet our global customers' needs. Our offerings include black tourmaline powder, gray tourmaline powder, and tailored functional mineral powders based on raw material and customer preferences.

For international buyers, key factors such as stable particle size distribution, clean packaging, low moisture content, consistent color, and reliable supply are essential. WANCHENG MINERAL focuses on controlled processing, thorough product inspection, export-ready packaging, sample support, and technical communication to assist customers in selecting the ideal tourmaline powder for their marketplace.

Frequently Asked Questions

Q What are the primary chemical components in this material?

The material is primarily composed of Silicon Dioxide (SiO2) at 32% - 45% and Aluminum Oxide (Al2O3) at 20% - 35%, which together form the primary structural silicate and alumina matrix.

Q Why is Boron Oxide (B2O3) a significant component?

Boron Oxide (B2O3) typically ranges between 5% and 12%, serving as a distinctive signature component characteristic of natural tourmaline mineral structures.

Q What causes variations in Fe2O3 and MgO content?

Variations in Iron Oxide (Fe2O3, 2% - 12%) and Magnesium Oxide (MgO, 1% - 10%) are primarily determined by the specific mineral species, coloration grade, and the geological origin of the raw ore.

Q Are trace elements like TiO2 kept under strict quality control?

Yes, Titanium Dioxide (TiO2) remains present only in trace quantities as a controlled impurity to ensure high chemical stability and consistency in specialized industrial applications.

Q What does the "Loss on Ignition" (LOI) value indicate?

The Loss on Ignition ranges from low to moderate, representing the volatile matter, bound moisture, or carbonate content driven off during high-temperature thermal processing.

Q What role do alkali components (Na2O + K2O) play?

Alkali oxides (Sodium Oxide and Potassium Oxide) account for 1% - 5% of the total composition, contributing to the balance of the mineral crystal lattice and its thermal behavior.
